Abstract

Procédé de purification d'hexafluorure de plutonium et nouveau produit ainsi obtenu. Dans ce procédé, on utilise une adsorption sélective des fluorures de fission nucléaire et/ou de l'hexafluorure de plutonium gazeux contenant les fluorures des impuretés, en laissant s'écouler ces produits à travers une couche d'adsorption se composant d'un composé ou d'un mélange de deux (ou plusieurs) composés choisis parmi l'hexafluoraluminate de sodium, le fluorure de zinc, le fluorure de nickel, le fluorure ferrique à une température élevée; le principe de la purification est basé sur le fait que les fluorures des produits de fission sont facilement adsorbés par l'adsorbant mais que peu d'hexafluorure de plutonium est adsorbé. La présente invention est particulièrement utile pour fournir un procédé pour purifier l'hexafluorure de plutonium pour le retraitement de combustibles nucléaires épuisés et pour la récupération de plutonium à partir de déchets.Process for the purification of plutonium hexafluoride and new product thus obtained. In this process, selective adsorption of nuclear fission fluorides and / or gaseous plutonium hexafluoride containing the fluorides of the impurities is used, allowing these products to flow through an adsorption layer consisting of a compound or a mixture of two (or more) compounds chosen from sodium hexafluoraluminate, zinc fluoride, nickel fluoride, ferric fluoride at an elevated temperature; the principle of purification is based on the fact that the fluorides of the fission products are easily adsorbed by the adsorbent, but that little plutonium hexafluoride is adsorbed. The present invention is particularly useful for providing a process for purifying plutonium hexafluoride for the reprocessing of spent nuclear fuels and for the recovery of plutonium from waste.
